I'm watching these on eBay, what do you guys think of them? I'm also wondering if they would fit me. I take a size 8 in U.S. sizing but a 38.5 in most Christian Louboutins. The lady selling them says she's between an 8 and a 8.5 and they fit her. These are a 39- would they fit? I don't have wide feet but I also don't have narrow feet.
